SEPARABLE JOURNAL BOX.

Application filed. February The present invention relates to separable journal boxes.

More particularly the present invention relates .to journal boxes suitable for use on the side frames of railway car trucks. In order to simplify the matter of repairs and replacement of parts, it is sometimes desirable to remove one or more journal boxes.

An object of the present invention is to provide a separable journal box which under normal conditions is securely locked in position, but which may be readily removed when desired.

A further object is to provide a journal box which may be removed with a tilting or rotating movement, but which will be se curely fastened in place under operating conditions.

A further object is to provide a separable journal box construction which will avoid the danger of accidental displacements when the truck is lifted, as for example by means of acr-ane.

Further objects will appear as the description proceeds.

Referring to the drawings Figure 1 is a view in side elevation of part ofa side frame having a separable journal box operatively associated therewith, which side frame and separable journal box embody the principles of the present invention;

Figure 2 is a sectional view taken along the plane indicated by the arrows 22 of Figure 1 and showing the parts in normal position;

Figure 3 is a'view similar to Figure 2, but showing the brass and wedge removed and the journal box tilted or rotated preparatory to the removal of said journal box.

The numeral indicates a side frame having the tension member 11 and the compression member 12. Said tension and compres sion members are connected together at the end portion 13 of the side frame, which end portion, as indicated in Figures 2 and 8, may take the form of a box section having the laterally extending flanges 14 and 15.

The numeral 14 indicates an axle, and the numeral 14 indicates the hub of a car wheel mounted thereon. Each end portion 16 of the axle 14 is formed to provide a member which supports the brass 17 and the wedge 18. Said brass 17 and wedge 18 support the 27, 192$. Serial No. 91,035.

journal box 19, which houses the bearing 16, brass 17 and wedge 18.

The upper portion of the journal box 19 is provided with an upstanding shoulder 20 adapted to abut the flange 14 of the end portion 13 of the side frame 12. Disposed in parallel relationship with the shoulder 14 is the hooked over portion 21 adapted to have hooking relationship with the flange of the end portion 13 of the side frame 12.

Then the axle 14 is supporting the brass 17, Wedge 18, journal box 19 and side frame 12, the parts will be positioned .as shown in Figure 2, with the flange 14 in abutting relationship with the shoulder and the flange 15 in hooking relationship with the portion 21 of the journal box 19. With the brass 17 and wedge 18 in place, it is impossible to tilt or rotate the journal 19 relative to the axle or to the side frame, and, accord ingly, the truck, which includes the side frame 12, may be lifted'as for example by means of a crane or a jack without danger of having the parts displaced relative to one another.

IVhen it is desired to remove the journal box 19, the side frame 12 may be jacked up,

whereby the weight of said side frame is removed from the brass 17 and wedge 18. It isa simple matter under these conditions to remove said brass and wedge, after which the journal box 19 will tilt or rotate to the position shown in Figure 3, with the lower inner edge thereof resting against the adjacent hub 14 of the car wheel. As will be noted from an inspection of Figure 8, the tilting or rotation of the journal box 19 has freed the shoulder 20 from engagement with the flange 14. Further lifting of the side frame 12 will cause rotation of the journal box about the axis defining the line of contact between the lower inner edge portion of said journal box and the hub 14". As the side frame is lifted, the rotation of the journal box will of course move the hooked over portion 21 out of engagement with the flange 15, whereby said flange 15 will free itself, allowing the journal box to drop. The j ournal box may then be readily removed from the axle 14 In again mounting the journal box 19 on the side frame 13, the above op erations may be reversed in order. In this connection it should be noted that the outer lower dust guard portion 22 of the journal box is bevelled off at its upper outer edge as indicated by the numeral 23, to provide additional clearance for the movement of said box. Inasmuch as the overall height of said guard portion 22 is not reduced, the space for retaining oil and Waste is not reduced from common practice.

It will be clear that the present invention provides a structure which permits ready assembly and disassembly, but which insures freedom from accidental displacement.

Though a preferred embodiment of the present invention has been described in detail, it will be clear that many modifications will occur to those skilled in the art. It is intended to cover all such modifications that fall within the scope of the appended claims.

I claim:

1. In combination, a car axle, a journal box therefor, filling means carried by said axle for supporting said journal box, a side frame having laterally extended flanges, said journal box having at its upper portion a shoulder having abutting relationship in a horizontal direction with one of said flanges, and a hooked over member having abutting relationship in a vertical direction with the other of said flanges.

2. In combination, a car axle, a journal box, filling means for supporting said journal box from said car axle, a frame having laterally extending flanges on the inner and outer sides thereof, said journal box having on its upper portion a shoulder having abutting relationship in a horizontal direction with the outer of said flanges and having a hooked over portion having abutting relationship in avertical dirertion with the inner of said flanges.

3. A journal box adapted to support a side frame having a shoulder extending across its upper surface, and a hooked over portion mounted in parallel relationship with said shoulder.

4. In combination, a car axle, a journal box, means for normally preventing rotating movement between said axle and journal box, and spaced abutn'ients on the upper side of said journal box adapted to engage a side frame, one of said abutments comprising a shoulder and the other of said abutments comprising a hooked over portion having hooking relationship with the side frame.

5. In combination, a car axle, a journal box tiltably mounted thereon, filling means for holding said box in non-tilting relation to said car axle, the outer lower dust guard portion of said journal box being bevelled on its upper outer edge.

6. In combination, a car axle, a journal box, means for normally preventing rotating movement between said axle and journal box, and spaced abutments on the upper side of said journal box adapted to engage a side frame, one of said abutments comprising a shoulder and the other of said abutnients comprising a hooked over portion having hooking relationship with the side frame, the outer lower dust guard portion of said journal box being bevelled on its upper outer edge.

7. In combination, a car axle, a journal box, filling means for supporting said journal box from said car axle, a frame having laterally extending flanges on the inner and outer sides thereof, said journal box having on its upper portion a shoulder having abutting relationship in. a horizontal direction with the outer of said flanges and having a hooked over portion having abutting relationship in a vertical direction with the inner of said flanges the outer lower dust guard portion of said journal box being bevelled on its upper outer edge.

8. In combination, a car axle, a journal box therefor, filling means carried by said axle for supporting said journal box, a side frame having laterally extended flanges,said journal box having at its upper portion a shoulder having abutting relationship in a horizontal direction with one of said flanges, and a hooked over member having abutting relationship in a vertical direction with the other of said flanges, the outer lower dust guard portion of said journal box being bevelled on its upper outer edge.
